The former fiancee of Scot Young, the divorced businessman who fell 60ft on to railings outside his £3million penthouse, has broken her silence to insist it was suicide.
Noelle Reno, an American socialite and reality television star, had been in a relationship with Mr Young, 52, for five years.
But in a blog post, she confirmed they had separated shortly before his "unexpected" death in December 2014.
The former model is understood to have had a blazing row with Mr Young shortly before he fell from his fourth-floor flat window in London's Marylebone.
It has been claimed that she angrily tried to order him to leave the flat after he turned up uninvited but later left the building, calling the police on her way out.
The circumstances behind his death have been the subject of various conspiracy theories.
It followed a High Court divorce hearing in which he was ordered to hand over £20 million to his former wife, Michelle Young, after a bitter six–year battle.
The father-of-two claimed he was "penniless" having lost his fortune in a highly secretive property development called Project Moscow but Mrs Young accused him of hiding away more than £400million.
Some aquaintances believe he may have been killed or ended his life due to business pressures arising from his secretive financial deals.
Miss Reno, 31, has been writing a blog on the Huffington Post website charting her worldwide travels called #12Countries12Months.
In a post published this week, she wrote: "My 12th and final trip of #12Countries12Months was meant to be completed with a weekend in Belgium accompanied by 3 of my most favourite girlfriends.
"Four days before we were to depart from Waterloo to Brussels somebody very close to me, named Scot Young, unexpectedly committed suicide.
"Scot and I had recently broken up after five and a half years of being together, most of which we were engaged."
She added: "One thing I know in the deepest depths of my soul, where all true wisdom resides, is that #12Countries12Months prepared me for this loss."
Miss Reno added: "I look forward to exploring this new journey in more depth as I come in to a new stage in my life."
Mr Young was the sixth member of a close–knit group to die in strange circumstances. Friends have expressed fears that they were all targeted by the Russian mafia.
Detectives are said to have dismissed claims that the entrepreneur died as part of a plot involving his connections to Russian oligarchs.
An inquest was opened and adjourned in December and no date has yet been set to re-open it.
Scot Young, the tragic tycoon who died falling from his fourth-storey London flat, owed millions of pounds to the Russian and Turkish mafia and was hung out of a hotel window by gangsters two years ago as a warning, a friend has claimed.
